Every faculty you have, your power of thinking or of moving your limbs from moment to moment, is given you by God. If you devoted every moment of your whole life exclusively to His service you could not give Him anything that was not in a sense his own already ... It is like a small child going to its father and saying, 'Daddy, give me sixpence to buy you a birthday present.' It is all very nice and proper, but only an idiot would think that the father is sixpence to the good on the transaction.
